Firstly, can the Atlassian account name i.e. <account-name>.atlassian.net, be renamed?
If so, if the account name is changed, will this then break existing links between Confluence, Jira, & BitBucket ?
Or is there a way to change the account name and/or fix the links without manually editing every Jira card, Confluence page, BitBucket issue?
Thank you for reaching out to the Community!
This feature is currently being tested and rolled out to Cloud instances. We will need to have a look at your instance itself in order to tell if it would be eligible for such a change.
Have a look here for more information:
I would recommend that you reach out to Cloud Support directly so that they can assist you with this.
I don't have the exact details on how the rename is working behind the scenes, but my assumption would be that it shouldn't break your Bitbucket Cloud connection. In the event that it does, the fix should be fairly easy. The support team will be able to confirm this information with you.
